Embodiment 1
[0028] Example 1: Determination of fingerprints of Radix Astragali medicinal materials
[0029] 1. Instruments: Agilent 1260 high performance liquid chromatography, G1311C quaternary pump, column thermostat, G1316A, G1315D, DAD detector, Agilent Zorbax Eclipse XDB C18 column (4.6×250mm, 5μm). The mass spectrometer system is an ESI-MSn mass spectrometer (Bruker).
[0030]Reagents: Acetonitrile was chromatographically pure (Burdick&Jackson, Honeywell International Inc., USA), glacial acetic acid was chromatographically pure (Tedia company Inc., USA), water (Millipore, Bedford, MA, USA), and other reagents were analytically pure (Sinopharm Group Chemical Reagents Ltd). Verbacosin, formononetin, and formononetin reference substances were purchased from China Biological Products Co., Ltd. All samples are reserved in the Sample Room of the Modernization Center of Traditional Chinese Medicine, Shanghai Institute of Materia Medica, Chinese Academy of Sciences.
